Abstract
Abstract A 13 C Fourier transform (FT) NMR study of trimethyl(phenylethynyl)silane gives new evidence for ( p → d ) π bonding or equivalent interaction between bonded carbon and silicon atoms. Pulsed FT operation allows detection of 29 Si 13 C spinspin coupling observed as 2.3 % 29 Si satellites in 13 C spectra. The one-bond 13 C 29 Si coupling constants for seven compounds were found to be roughly proportional to “ s ” character on carbon, ranging from 50.2 ( sp 3 ) to 83.6 Hz ( sp ).
